Thesis (MSc)--University of Stellenbosch, 2001.<br>ENGLISH ABSTRACT: Experiments using the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), were conducted to determine the mortality of males and females and the ovipositing ability of females fed on two diets. The sugar diet consisted of 5: 1 sugar:protein and the protein diet consisted of 5:1 protein: sugar. Dilutions of 80%, 60%, 40%, 20% and 10% with water of both diets were also provided to the flies. Female longevity was shorter than male longevity. There was no difference in female longevity between fruit flies fed on the tw

Résumé :

Fruit thinning is critical to the success of apple industry because most apple trees are prone to biennial bearing characterized by heavy bloom and over-cropping in the â onâ year and low or no cropping in the â offâ year. Fruit thinning can improve fruit size, increase return bloom, and reduce alternate bearing habit of apple trees. Chemical thinning has been widely used as a horticultural practice by growers for years in apple and other fruit production. However, its thinning results are often variable and very difficult to predict since parameters as well as their interactions (e.g. c

Texte intégral

Résumé :

Rhodococcus has diverse metabolic capabilities, such as delaying ripening of certain climacteric fruit. Nitrile hydratase (NHase), amidase, 1-aminocyclopropane-1-carboxylate deaminase (ACC deaminase), cyanidase, and β-cyanoalanine synthase-like enzyme (βCAS-like) are possibly involved in fruit ripening. The activity of these enzymes in Rhodococcus rhodochrous DAP 96253 cells were induced with selected multiple inducers (i.e. cobalt and urea). This research showed that the supplementation of selected sugars, i.e. trehalose and maltodextrin in growth media and storage buffers of R. rhodochrous

Résumé :

The effect of fruit removal from cantaloupe was studied under field conditions in a soil naturally infested with Monosporascus cannonballus. Fruit removal resulted in greater sugar accumulation in the cantaloupe roots compared to the roots from plants on which the fruits were allowed to develop normally. Individual, total, and combined root carbohydrate levels were greater in plants without fruit than in plants with fruit. Five major sugars (stachyose, raffinose, sucrose, glucose, and fructose) were found in the cantaloupe roots. Stachyose concentrations were higher than all the other sugars i

Cucurbit yellow stunting disorder virus (CYSDV) is a relatively new virus affecting cantaloupe production in South Texas and worldwide. No resistant commercial cultivars are available. A cross of Dulce (susceptible) x TGR1551 (resistant) was made and populations were developed for screening. Although no complete resistance was recovered, TGR1551 showed some tolerance and may be useful in breeding efforts. Sugar components such as sucrose, fructose, glucose, and total soluble solids are major factors in determining mature melon fruit sweetness, and Vitamin C is important for human health

Résumé :

Tomatoes are widely produced and consumed due to their nutritional content and versatility. However, the tomato is a soft fruit liable to damage and flavour deterioration. Hence, the main challenge for the tomato producing industry is to prevent the high loss incurred during harvest, handling and transportation of the crops. The objective of this study was to investigate the overall nutritional implication of controlled storage of tomatoes using ozone on the ripening process and the basic nutritional components of tomatoes.

Résumé :

[ES] La citricultura se enfrenta a escenarios ambientales cambiantes que provocan diferentes estreses bióticos y abióticos que pueden dificultar la producción o afectar a la calidad de la fruta. El patrón sobre el cual se injerta una variedad específica es una importante herramienta para mejorar su adaptabilidad a cada área de cultivo. En la presente Tesis se realiza el estudio del efecto del patrón sobre la calidad físico-química y nutricional de la fruta en variedades de gran interés comercial en la actualidad, mandarinas 'Clemenules' y 'Tango' y naranjas sanguinas 'Tarocco Rosso' y 'Moro'

Orientador: Eduardo Paulon Girardi<br>Resumo: Imprescindível na manutenção das condições de acumulação do capital, o regime alimentar e a sua etapa corporativa fazem surgir os impérios alimentares, modos de ordenamento que trazem em si o potencial de controlar integralmente a produção, distribuição e consumo de alimentos. Em que pese a sua abrangência global, o controle atualmente exercido pelos impérios alimentares se realiza, efetivamente, na escala de cada um dos municípios produtores, o que evidencia a necessidade não apenas da articulação de escalas para o entendimento dos processos, mas,

Résumé :

Para o cenário da sustentabilidade da cana um dos problemas é o tráfego indiscriminado de rodados sobre as soqueiras, especialmente na colheita mecanizada, devido a desalinhamentos das fileiras de cana e dificuldade de manutenção dos veículos e composições devidamente afastados destas. Assim, as tecnologias de direcionamento automático estão ganhando espaço no setor sucroalcooleiro. No cenário da citricultura a implantação de um pomar é uma etapa de extrema importância econômica, uma vez que estão envolvidas diversas operações mecanizadas. O alinhamento das fileiras é feito manualmente, etapa

Ces études ont pour but de décrire les effets des sources carbonées, azotées et les vitamines sur la production d’acide lactique.

Résumé :

It has been suggested that fruit features such as nutrient content, size and colour have co-evolved with dispersal agent behaviour, physiology and morphology. Avian nectarivore feeding ecology is relatively well studied; however, less is known about fruit selection in avian frugivores. Previous work highlights the importance of individual factors that contribute towards fruit preferences, but few studies bring these factors together. Consequently the aim of this dissertation was to attempt this in terms of frugivory by investigating behavioural, physiological and morphological aspects of fruit

We compared four structures, three etched LPGs with the concentration of 20%, 25%, and 30%, respectively, and the unetched LPG. The experiment was designed to perform LPG sensor testing with different types of fruits. And the result showed that the wavelength will shift to long wavelength, when juice content increased.

According to the official data shows that only 44% of crops loss was compensated by redressing subsidy from government. It is actually not enough to offset farmers’ physical damages.

The accumulation of hexose in tomato fruit is realised and regulated during the rapid period of fruit growth. With outer pericarp as the targeted fruit tissue, the aims of this investigation were (1) to determine the cellular pathway of postphloem sugar transport; and thereby (2) attempt to identify the cellular processes controlling hexose accumulation in the storage parenchyma cells. The cellular pathway of postphloem sugar transport was elucidated in fruit at 13 to 14

The results showed that there were significant negative correlations between fruit weight and total soluble solids and titratable acid of pineapple fruit harvested from the same area. However, the above correlations were not significant in fruits harvested from different areas, which suggested that environmental and cultural factors had significant impacts on those characteristics, even more than genetic factors did.
